CAR-COUPLiNG.

SPECIFICATION forming part of Letters Patent No. 321,677, dated July 71 1885.

Application filed May 20, 1855.

To all whom may concern.-

Be it known that l, GEORGE W. BOLTON, a citizen of the United States, residing at Detroit, in the county of Wayno and State of Michigan, have invented certain new and usefnl Improvements in Oar-Oouplei's; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had iO the accompanying drawings, and to letters or Iigures of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a representation of a plan view. Fig. 2 is a vertical section. Fig. 8 is a horizontal section. Fig. iis a detail view, and Figs. 5, G, and 7 are views of moditieat-ions.

This invention relates to car-couplers; and it consists in the construction and novel eonr bination of parts, as will be hereinafter fully described, and particularly pointed out in the claims.

Referring by letter to the accompanying drawings, A designates the bumper ot the car, and B B" are the gnidetimbers between which the stem C of draw-head works when the drawhead is in place on the car. I) is a spring which encircles the stem O of the draw-head, near the inner end of said stern, and receives and relieves the cars of the shock attending the meeting of two cars, either when coupling them or while the train of cars is in motion. The stem C and the jaws E and F of the draw head are cast integral, the arm E being made longer and heavier than the arm F, both arms being slightly curved, as shown in Fig. l. The arm E is cast hollow from its forward end back nearly to the termination of the outside curve, E, at the stem of the draw head, and in this hollow arm E', which is open at both ends, is secured a dat curved spring, G, a screw, G, at the rear end of the spring, being employed to hold said spring in place in the arm E. At its forward end the arm E is provided with lugs or bearings II E, between which the tongue I of the pivoted head I rests or plays when the head I is operated or is at rest, as the case may be. The pivoted head Il is provided with horizontal side iiange, I2 I3, having end lugs, I" I, which are pivoted by a rod, I, in rabbets I7 I7 in the sides of the arm E.

(No model.)

The arm E of the drawhead is provided with a shoulder, J, and at this shoulder J is provided vertical integral lugs K K, between which the angular retaining' and releasing catch L is pivoted.

Then it is desired to retain the draw-heads in the coupled position, the pivoted heads I of both draw-heads are released by drawing @C upon the levers M M, which are pivoted to the car-body in a position to bc reached by the operator without entering between the cars. Said levers may be operated either from the tops or the sides of the cars, as may be desired.

The retaining and releasing catch L is provided with an arm, L', which bears upon the spring G near its forward end, and the immediate forward end of the spring G bears up aga-inst the Outer face ot' the tongue I of the head I and forces the head inward when the releasing and holding catch L is disengaged from the vertical notch N in the faeeof the pivoted head I. Near its upper end thereleasing and holding catch L is provided with a projection, U, which, when the pivoted head I has been released by operating the lever M', is fulerurned to the eanbody and is connected to the arm Q of the releasing and holding catch L by a rod, M. This lever and the rod M can he operated to both open and close the pivoted head I without entering between the cars. Y

In the modification the longer arm ci of the draw-head is provided with a vertical slot, b, in which the lever c, for locking and holding the pivoted head d, is fulcruined. The pivoted head d is provided on its upper end with arearwardly-projecting inclined arm, e. The pivoted head (l in this modification is held in the closed position by a spiral spring, @'which bears against an arm, f, of the pivoted head d, and this spring e is put to place through a hole, e, in the outer wall of the longer arm a. A notch, f, is provided at the junction of the inclined arln c with the pivotcd head d. A locking and releasing lever, g, is fulcrumed in a vertical slot, b, in the longer arm a of this draw-head, and is turned to have its arm rest roo in the notch f when it is designed to hold the pivoted head d open. This lever g is moved out of the notch f when the pivoted head (l is to be closed. Between the jaws of the drawhead is provided a buffer-plate, i, provided with a vertically-slotted stem, i, which extends back into the hollow stem i* of the drawhead i and limits the forward movement of the buffer-plate z', the rear walls of the jaws of the draw-head limiting the backward movement of the buffer-plate.

As in the construction first hereinbefore described, the lever for locking and releasing the pivoted head d may be operated from either the sides or the tops of the cars, or both, if desired.

A car provided with the modified form of car-coupling may be readily coupled with a car having the form of coupling,` first hereinbefore described, as they are so nearly similar in construction and operation as to be used interchangeably.

In a former patent-viz., No. 221,440-I have employed pivoted L-shaped jaws to hold the coupling-link and, to also release it at the proper time; but in that instance two of said jaws were used in each drawhead, while in the instance above described but one conpling-jaw is employed in each drawhead,which materially lessens the cost of constructing the car-couplings.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. The combination, with the draw-head having the shorter arm and the longer hollow recessed arm, of the pivoted spring-actuated locking and releasing head and the pivoted releasing aud holding` catch, substantially as specified.

2. The combination, with the draw-head having` the shorter curved arm and the longer hollow slotted and recessed curved arm, of the locking` and releasinghead, the pivoted springactuated locking and releasing head, the pivoted catch and stop, and the operatingdever, and the rod connecting` the lever and pivoted catch and stop, substantially as specified.

In testimony whereof I aflix my signature in presence of two witnesses.

GEORGE XV. BOLTON.
